[svn-r10971] Purpose: Bug fix

Description: See details from Bug #213.  Family member file size wasn't saved
anywhere in file.  When family file is opened, the first member size determine
the member size.

Solution:  Hopefully, this is the last step of checkin for this stage.  This step
mainly enables h5repart tool to be able to convert file driver from family to
sec2.  Because the library saves family information in file, in trying to convert
to sec2 driver, the library simply change the address of driver information to
undefined so that the driver information block can be ignored.  This step also
updates the reference manual of H5Pset_fapl_family() and h5repart.

In the fifth step of checkin, backward compatibility with v1.6
is tested.  A family file created was created with the v1.6 library and opened
with this version of the library.

In the fourth step of checkin, a test suit is added for h5repart,
including a program to generate the test files, a script file to run h5repart,
and a program to verify repartitioned files can be opened by the library.

There's a change from the first step of checkin.  Family name template is no
longer saved in the superblock because different pathname can make the name
different.

In the third step of checkin, h5repart has been modified.  If h5repart is used
to change the size of family member file, the new size(actual member size) is saved
in the superblock.

In the second step of checkin, multi driver is checked against the driver
name saved in superblock.  Wrong driver will result in a failure with an error message
indicating
multi driver should be used.  This change includes split driver because it's a special
case for multi
driver.

In the first step of checkin.  Family member size and name template(unused at this stage) are saved
in file superblock.  When file is reopened,the size passed in thrin superblock.  A different size
will trigger a failure with an error message indicating the right size.  Wrong driver to open family
file will cause a failure, too.


Platforms tested: h5committest and fuss.
